Overview

This code snippet shows how to delete a message from the Inbox using the Messaging Platform Service for S60 Web Runtime introduced in S60 5th Edition.

The device.getServiceObject("Service.Messaging", "IMessaging") method is used to get access to the service object for the Messaging Service API.

Source

The HTML select component contains the messages:

<select size="5" id="messageList" multiple></select><br />

var serviceObj = null;
 
// Initializes the widget
function init() {
    try {
        serviceObj = device.getServiceObject("Service.Messaging",
            "IMessaging");
    } catch (ex) {
        alert("Service object cannot be found.");
        return;
    }
}

// Removes the message which is selected in the list box.
function removeMessage() {
    // Get a reference to SELECT object which contains the list of messages
    var messageList = document.getElementById("messageList");
 
    var criteria = new Object();
    // Find the selected messages
    for (var msgIndex = 0; msgIndex < messageList.length; msgIndex++) {
        if (messageList.options[msgIndex].selected) {
            // Get message id of the selected message
            var messageId = messageList.options[msgIndex].value;
            // Radix of message id integer value
            var radix = 10;
            // Get numeric representation of the message id
            criteria.MessageId = parseInt(messageId, radix);
            // Delete the message
            var result = serviceObject.IMessaging.Delete(criteria);
            if (result.ErrorCode !== 0) {
                alert("Error in deleting messages");
                break;
            }
            // Remove message record from selection list
            messageList.remove(msgIndex);
            msgIndex = msgIndex - 1;
        }
    }
    getMessageList();
}

Postconditions

The selected SMS or MMS messages are deleted.
